Assuming the diodes to be ideal in the figure, for the output to be clipped, the input voltage $${V_i}$$ must be outside the range

In the circuit shown below, the knee current of the ideal Zener diode is $$10$$ $$mA.$$ To maintain $$5 V$$ across $${R_L}$$, the minimum value of $${R_L}$$ in $$\Omega $$ and the minimum power rating of the Zener diode in $$mW$$ respectively are

A voltage $$1000\sin \omega t$$ Volts is applied across $$YZ.$$ Assuming ideal diodes, the voltage measured across $$WX$$ in Volts is

A clipper Circuit is shown below

Assuming forward voltage drops of the diodes to be $$0.7V,$$ the input-output transfer characteristics of the circuit is
